Vaisala to Supply Next Generation Dropsondes for National Oceanic and Atmospheric Administration in USA

Vaisala and the National Oceanic and Atmospheric Administration (NOAA) have signed a 5 year supply contract for the delivery of next generation GPS dropsondes used for hurricane reconnaissance, hurricane research and storm track forecasting by the US National Hurricane Center. The estimated value of the deal is USD 9.2 million.

"We are extremely pleased that NOAA has chosen Vaisala to supply their next generation dropsondes," says Martti Husu, Senior Vice President of Meteorology Business Area in Vaisala. "The new design of the dropsondes has been developed by NCAR (National Center for Atmospheric Research) and they selected Vaisala's calibrated radiosonde sensor modules for use in the new design. The contract strengthens the successful co-operation that we have with one of the world's leading research institutes in this field."

Vaisala Dropsondes measure pressure, temperature and relative humidity as well as profiles of the wind fields derived from GPS signals. These specialized meteorological sensors are designed to cover a complete range of atmospheric conditions.

Dropsondes are released from aircrafts flying at altitudes anywhere from near the sea surface to their maximum operating capability, and they are mainly used for targeted observations over the ocean. They provide data for severe storm trajectory and intensity prediction.
